Thread: 1.8 running issue, is it fuel related ?

Some time ago I acquired a 1999, 1.8 liter Freelander 1, It had a blown motor and had been sitting in a shed for ages, it belonged to a local old couple who had just parked it up and left it when it broke down. It now has a reconditioned motor (with upgraded head gasket and the modified thermostat and pipework) new battery, fuel pump and filter.
However it still has an annoying problem, it runs and drives fine most of the time but every so often, when driving on the open road when easing of the right pedal. It loses power and runs sort of flat, losing power under load but revving freely with the clutch in, it then runs roughly ( if it was my SIIa I would be thinking, running out of fuel) for a couple of hundred meters up a kilometer or so and then runs fine again. If it does this around town it stalls and is a pig to get to start again, the easiest way to start it is to disconnect the fuel cut off switch and turn it over it is the fairly slow to start, almost one cylinder at a time and will stall again if the fuel cut off switch is not reconnected fairly quickly, once reconnected it settles down and runs fine again (the fuel cut off switch has been replace with no real change to the problem). There is no pattern to this issue, it can go a day or so without doing it, then do it twice in the space of half an hour or I can go over 100 ks without a problem and the next day it will get 2 ks down the road and start doing it.
Open to any ideas those of you in the know might have as to the source of the problem and its solution.

It's a accumulator. They don't have a return fuel line from the fuel rail. This is why the pressure regulator is in the tank.
